Attention fans of id Software: you will not want to miss QuakeCon 2011!

To mark two decades of gaming excellence, key figures from id are coming together for the “20 Years of id Software” panel, a lively look back at one of the most storied studios in gaming.

John Carmack, Todd Hollenshead, Kevin Cloud and Tim Willits will all be on hand to tell their tales on the main stage, with G4TV’s Morgan Webb hosting the proceedings. Following the hour-long panel, the id guys will stick around for a signing session with fans. It’s all going down at 2:30pm on Friday, August 5 in the Grand Ballroom.

But before the panel even begins, we’re giving you a chance to participate. Are you a collector of id-related materials? Did you have your picture taken with John Carmack once — or did you get your Quake box signed by the dev team? Send in QuakeCon photos, pictures of your id game collections, your favorite screenshots — anything related to id — to “bethblog@bethsoft.com” under the subject “id 20th” and you may see your image featured on the big screen during the event. We’ll be giving away id-related posters to the people with our favorite contributions, so good luck!

When is information like this going to be published to the event schedule? I’m trying to determine what days and talks I want to take off work for, but the schedule contains next to no useful information at this point.
